Assistant Professor of Volcanology at the Geophysical Institute in Fairbanks, John Dehn described at the Wendy Williamson Auditorium how infrared technology has improved studies of recent eruptions. Volcanologists can now obtain more accurate readings a safe distance away from the hazardous lava flows and incinerating ash clouds using infrared cameras. In addition, by studying daily images from the cameras, scientists can prepare for and asses the intensity and extent of future blasts.
